A state correction officer and a selfie-happy Instagram user were part of a crew that waged a series of armored car heists in the Bronx over the past several months, according to the feds.

Their most recent heist ended with a wild shootout on a Bronx street last month.

A joint FBI-NYPD task force on Thursday busted three men — Michael Santiago, 29, a correction officer at the Downstate Correctional Facility in Fishkill, Bruce Collazo, 20, and Kenneth Smith, 34. They were charged with three robberies — one on Aug. 24, the others on Dec. 4 and 15. All three face life in prison.

Just one day after the first heist, Collazo, who goes by the nickname “Tonz,” posted a photo on Instagram of a large wad of cash, wedged between red high-top sneakers, federal authorities said.

In other photos, he posed with a gun, and what looks like packets of marijuana.

The second armored car robbery took place at at the Chase Bank at Westchester and Boynton Aves. on Dec. 4, according to authorities.
